OF DES MOINES, IOWA SYRING-E Application led October 6, 1931. Serial 1010.567323.

This invention relates to improvements in syringes and has particular reference to a fountain syringe employed in the treatment of internal organs such as the vagina.

An object of the invention is to provide an improved syringe of simple and practical construction which will be effective in the treatment of the vagina and other internal organs.

Another object is to provide an apparatus for simultaneously distending and applying heat and medicament to the vagina.

The above and other objects will appear more clearly from the following detail desoription; when taken in connection with the accompanying drawing7 which illustrates preferred embodiments of the inventive idea.

In the drawing- Figure 1 is a side elevation of one form of the device;

Figure 2 is a fragmentary longitudinal sectional view;

Figure 8 is an end elevation;

Figure 4 is a section on the line 4-4 of Figure 2; and

Figure 5 is a view similar to Figure 2 showing a slightly diiferent form of the invention.

Referring particularly to Figures l to 4 of the accompanying drawing, the syringe is shown as comprising a hollow body portion or head, generally indicated by the numeral 6, made of a hard rubber composition or other suitable material and including the inner and outer walls? and 8 combining to form a medicament-receiving compartment 9. The inner wall 7 is of cylindrical formation and denes a centrally disposed opening in the head. The outer wall 8 is of tapered formation and at its outer enlarged end is internally screwthreaded to receive a removable end closure 10 also having a central opening 11 alined with the opening formed by the inner wall 7. The end closure 10 has mounted therein a connection 12 utilized for the purpose of introducing a medicament into the compartment 9 from a suitable receptacle.

At the inner reduced end of the head 6 the same is provided with a plurality of spaced openings arranged in a circle and in which connections 13 are mounted for receiving thereover the open ends of the flexible tubes lthe inner wall 7 of extends longitudinally of and between the L J 14, commonly known as Dakin tubes. These tubes are provided with perforations 15 throughout their lengths; the perforations being more numerous adjacent the free or closed ends of the tubes than at the open ends ,v

thereof, whereby the medicament from the compartment 9 will flow through the perforations in greater quantities at the free ends of the tubes, so that when the device is in proper p ostion the most beneficial results will be derived.

In order to secure distension and apply heat to the vagina while using the device, the syringe further includes a iieXible and elongated receptacle 16 made of any suitable s material and open at one end. This receptacle has the portion thereof adjacent lits open end mounted in the opening formed by while the remainder thererlhe plug is provided longitudinally Vthere-..J

of with passages 18 and 19 in the outer ends of which are disposed the inlet and outlet connections20 and 21 respectively. The connection 2O is designed to be connected to a hot water bag or other suitable receptacle so that the receptacle 16 may be filled with heated water or other fluid to distend the same and at the same time apply heat to the parts to be treated. The inlet passage 19 is made slightly larger in diameter than the outlet passage 18 so that a back pressure will be created bythe Water circulating through the device which will maintain the receptacle 16 in a distended condition. It will be obmay be made longer than the passage 18 by inserting one end of a short connection (not shown) similar to the connection 2O in the inner end of said passage 19.

`vfous that, if so desired, the inlet passage 19 A In the operation of the device, after the same has been properly positioned in the vagina, the heated Water may be permitted to circulate through the receptacle 16 and out of the passage 21 into a basin or other receptacle to secure proper distension and apphcation of heat. At the same time the medicament may be permitted to flow into the com artment 9 and from thence through the pe orations in the tubes 14: to the parts b eing treated. Q

n Figure 5 there is shown a slightly d1fferent form of securing means or the recep-4 tacle 16 and plug 17 wherein the closure 10 is provided with an annular flange 22 having a bayonet slot 23 therein for receiving a pin 24 carried by a reduced portion of the plug 17.` With this construction the plug is securely held in position and at the same time is effective in maintaining the receptacle 16 in proper position.

What is claimed is:

1. In a syringe, a body portion including inner and outer walls forming a medicamentcontaining compartment, a plurality of perforated tubes carried by said body portion and having communication with said compartment, and means carried by said body ortion for applying heat to and securing istension of parts to be treated.

2. In a syringe, a body portion including inner and outer walls forming a medicamentcontaining compartment, a plurality of perforated tubes carried by said body portion and having communication with said compartment, and a flexible fluid-containing receptacle carried bv said body portion and extending longitudinally o and in close proximity to said tubes. l

3. In a syringe. a body portion provided with a compartment and havingr an opening therethrough, a removable end closure for said compartment surrounding said opening, a plurality of perforated tubes carried by vSaid body portion and communicating with said compartment, a liquid-containing receptacle having one end disposed in the openin in said body portion and engageable with said end' closure and the remainder thereof arranged contiguous to said tubes, and a plug insertable into said opening and end of said receptacle to wedge the latter between said plug and the Wall of said opening and said closure.

4. In a syringe, a body portion provided fined within an area defined by said tubes, and a tapered lu insertable into said open- ,ing and end o said receptacle to wedge the latter between said plug and the wall of said opening and said closure.
